ASP.Net MVC不会为ajax调用映射参数

我想在ASP.Net Core 1.0中发送带有多个参数的请求（我不知道这是否重要）。

我有以下模型：

[DataContract]
public class RegistrationConfigContract
{
    [DataMember]
    public string ServiceType { get; set; }
    [DataMember]
    public int BatchTimeout { get; set; }
    [DataMember]
    public int BatchSize { get; set; }
    [DataMember]
    public ActorFinishingTypeEnum FinishingType { get; set; }
}

我有以下控制器方法：

public void SendRegistration(string nodeName, NodeTypeEnum nodeType, RegistrationConfigContract model)
{

}

我也有一个JS试图调用它：

function sendRegistration(nodeName, nodeType) {
    var model = {
        ServiceType: $("#serviceType").html(),
        BatchTimeout: $("#batchTimeout").html(),
        BatchSize: $("#batchSize").html(),
        FinishingType: $("#finishingType").html()
    };

    var request = {
        nodeName: nodeName,
        nodeType: nodeType,
        model: model
    }

    //$.post('@Url.Action("SendRegistration")', request);
    $.ajax({
        url: '@Url.Action("SendRegistration")',
        type: "POST",
        dataType: 'json',
        data: JSON.stringify(request),
        async: false,
        cache: false,
        traditional: true,
        contentType: 'application/json'
    });
}

但是根据Chrome / Edge调试器，在服务器端，我总是得到null，而在JS端，一切都很好。

我在这里做错了什么？我尝试使用通过Google搜索的代码来解决此问题，但是它不起作用。

原始HTTP请求：
